Description

ADM S. p. A.

Quinto Stampi - Via Po 30, Rozzano (Milano) - ITALY

The invention relates to an output part for aerosol valves, with a ring surrounding the base of an aerosol valve and a wall part having a seat for the valve tappet and a discharge opening, which is connected to the ring a guarantee lock is connected. The dispensing parts attached to aerosol valves often have warranty closures provided, which have the purpose of fraudulent removal of the substance in the container to prevent. Such tamper-evident closures are usually created by having a metal ring covering the bottom of an aerosol valve, is connected to the actual dispensing part by means of thin strips of material, which break when the output part is actuated. These thin strips are usually on two or two provided more very limited places where easily breakable narrow material parts with the wall part connect to the ring.

The known dispensing parts provided with guarantee closures have various disadvantages. The main disadvantage consists in the difficulty of determining whether the seal has been broken. This is usually the first time possible after a thorough inspection. Furthermore, the guarantee closures are easily fragile, so

-A-

that they can break accidentally. Finally, the assembly of the dispensing parts is on the aerosol valves very carefully to prevent the bridges of the guarantee clasp from tearing.

The object of the invention is to provide an on aerosol valves to create fastening output part with a guarantee lock that is strong and cannot break accidentally and has a simple problem- * loose assembly with the valve, both without special tools and automatically, allows.

To solve this problem, the invention provides that the guarantee closure has at least one tear tab with projections for the attack of the fingers a user is provided, and that the pull tab

1 along part of the edge of the ring in this way runs that the seat and the outlet port supporting Wall part is firmly anchored on the tear tab.

The output part according to the invention ensures that a | i

Breaking the guarantee lock immediately and 1

is easily recognized, so that fraudulent removal _s

of the substance in the container is not un- | knows is possible.

The output part provided with the guarantee lock is simple and can be manufactured at low production costs as well as reliable in use.

The fact that the guarantee tongue extends over a considerable part of the way that when started

Container is designed as a gap to allow sufficient pivoting movement of the wall part connected to the ring to enable, it is ensured with an intact guarantee lock that by simply pressing the control button, the guarantee lock usually cannot be broken. Rather, this is done by tearing it off the tongue, as a result of which the wall part is then released and pivoted around its bridge can be.

In the following, a preferred embodiment of the invention is explained in more detail with reference to the drawings explained.

Show it:

Figure 1 is a perspective view of the on an aerosol container mounted output part, fastened with an integral guarantee lock,

FIG. 2 shows a view of the dispensing part while the guarantee closure is being torn open, and FIG

FIG. 3 shows a longitudinal section through the dispensing part along one through the container axis and the axis of the dispensing opening continuous plane.

The output part shown in the drawing has a metallic ring or outer jacket 1, on whose free lower edge an inwardly directed rib is provided which can be pressed over the beaded edge 10 of the bottom of a valve which is on the container 8 or the spray can is attached. The output part also has a horizontal flat wall 3 0 the underside of which has a seat for receiving the plunger 11 of the aerosol valve is shaped. Furthermore, the wall 3 is a hollow narrow tube 4 and an actuating button 5 molded, both of which protrude upwards. The wall 3 is separated from the ring 1 by a groove (on which the Ring is at a distance from the wall 3), and is connected to the ring by a flexible tongue 2 and a pull tab

tied together. The free ends 7 of the tear tab are high and can easily be gripped with your fingers. the Tongue 6 represents a continuation-like approach of the groove 12 and surrounds the disc 3 together with this groove, the narrow tube 4 and the button 5 lying on either side of the flexible bridge 2. The tongue 6 is with the ring 1 and the disc 3 are preferably connected by weakening lines, where the material thickness of the Output part is smaller than on the ring 1 or the disc 3. Due to its length, the tongue 6, however a firm and secure anchorage for the disc on the ring 1, so that before breaking the guarantee lock (Figures 1 and 3) the dispensing part is very stable overall, so that it can be easily mounted on aerosol valves can be without the risk of inadvertently breaking the guarantee lock, even if an automatic machine is used for such an operation.

Unlike the well-known guarantee closures, in which the connection between the metal ring and the movable one Part is limited to only two or three places of limited extent, the described guarantee lock do not break open unintentionally and the closure can also be broken by remote detection to be established. If the guarantee seal is to be broken, the protruding end 7 is the Tongue grasped with the fingers (Figure 2) and pulled up so that the tongue 6 is completely torn off. In In this state, the actual output part 3, 4, 5 is only connected to the ring 1 at the flat bridge 2,

and it can go around the bridge in the usual way vibrate to dispense the substance contained in the container 8.

An empty channel 12 of relatively large width is created between the ring 1 and the flat wall 3, which the dispensing process facilitated, since the wall 3 cannot be obstructed by the ring 1 in this way. Furthermore can the absence of the locking tongue 6 is easy to see can be determined, whereby a fraudulent breaking of the output part is recognized immediately.

The output part described is particularly suitable for foam products, especially in the food sector, however, the invention can also be applied to containers and dispensing parts of other types.
